Abstract
Two-dimensional projection measurements are formed of the NMR activity of a selected region of a volume. These represent different properties of the materials within the volume including density and relaxation times. The measurements of the different properties are processed to produce projection images of specific materials within the volume. Projection images are also obtained of moving materials only to provide isolated vessel images.
